To all 'whom it may concern Be it known that-we, ARTHUR t). CULVER and ALBERT W. RUSSEL, citizens ot' the AUnited States of America, residing at De! troit, in the county of Wayne and State oit Michigan, have invented certain new and 4further, to hold said strap uniformly spaced vas to reduce the clearance required.

from the drum when in released position so In the drawings: Figure l is a central section through the brake mechanism; Fig. 2 is a plan view thereof; and. Fig. 3 is a side elevation. f A is an axle of any suitable construction;

lB is the brake-head mounted upon said axle;

C is the wheel hub adjacent to the end ot'v the axle and connected to the revoluble axle shaft D; and E is a brake-drum secured' to the wheel'C and projecting laterally theres W'liere it is desired to apply the brake .both inside and VAoutside the drum, an inner brake-.shoe is used,-and is operated by suitable mechanism,`such as the rock shaft Gr. The outer brake is formed by a strap H `which surrounds the drum and is operated by suitable lever mechanism I.

'It is usual to provide van anchorage connection between the central portion of the brake strap andl the brake-head, while the ends' of the strap are'connected with. the leverrincchanisin. The anchorage connection is usually a laterally-extending bracket se.- curecl to the brake-head, and other brackets are. provided for the Tt'ulcrums of the lever Specification of Letters Patent.

connection. With our improved construction, 1n. lace oflaterally-extending brackets, the rake-head B is provided with an integral. flange il, which extends around the brake-strap and forms a housing therefor. This Flange is provided with an inturned edge K, which` is substantially in the cen.- ter oijthe brake-strap, and is machined to be concentric with the axis of the wheel and drum. rlfhe diameter of the ycircle is also sucl as to provide clearance for the. strap when released from contact with the drum, but this clearance is very small. It is nevertheless suiiicient to hold all portions of the strap out of contact with the drum, and the true circular form of the flanges and its concentric relation to the drum will hold the strap also in concentric relation.

What We claim as our invention is:

l. rlhe combination with a brake-drum,` of

a brake-head adjacent thereto, having a' laterally-projecting tiange with a circular edge portion concentric with the drum, and a brake-strap interposed between said flange and drum and held by the former inv concentric relation wlien in released position.

2. .The combination with a brake-drum, of a brake-head. adjacent thereto, a flange projecting laterally from saidhead, ,embracing said drum and having an inturned edge portion machined concentric with the drum, and a brake-strap surrounding said drum and retained in its released position in concentric relation by bearing upon said machined edge.

3. The combination with an axle and a wheel, of a brake-drum mounted upon said v. heel, a brake-head mounted upon said axlej and a braliestrapA embraced by said flange4v and supportedclin its released position by said machined edge with uniform clearance from the drum.
